GENEVA, August 17, 2012 - The London Olympic Basketball Tournament has had a significant impact on the FIBA Rankings for Men and Women with a number of teams making big leaps towards the top.

While the men's top five - USA, Spain, Argentina, Greece and Lithuania - remains unchanged, Russia have moved up five places from 11th to sixth following their bronze medal run in London.

Beaten quarter-finalists France, who fell to eventual finalists Spain, and Brazil, who lost to neighbours Argentina, moved up four places each to stand eighth and ninth respectively.

The African teams also moved up some places, with Nigeria up to 17th from 21st, while Tunisia jumped 10 spots, moving from 32nd to 22nd.

Olympic hosts Great Britain made the biggest leap of all, going from 43rd to 23rd, a 20-place improvement.

Meanwhile, for the women, the USA cemented their place as number one in the world with a fifth consecutive Olympic gold medal.

For the first time since 1996, Australia failed to reach the Olympic Final, but their bronze medal finish enabled them to stay second in the ranking.

The Opals shared the position with Russia but beat them for the third and final place on the podium in London and the Russians dropped down to third in the world as a result.

France, fresh off of their first-ever Olympic Final appearance, gained three places to climb up to fifth while Canada moved from just outside the top 10 to just inside it (11th to 9th).

A number of Olympic debutantes also did well for themselves. Turkey, who won four of their six games and came agonizingly close to reaching the Semi-Finals, moved up to 13th, an eight-place improvement.

Croatia's women registered their first-ever win in the competition and improved from 31st to 21st.

Angola didn't manage a win in the Olympic Basketball Tournament, however their efforts were well rewarded as they improved from 27th in the world to 23rd.

Great Britain's women had the biggest leap of all, going from 49th to 24th.
